Product Description:
Using the Schottky Barrier principle with a Molybdenum barrier metal.
These state-of-are geometry features epitaxial construction with oxide
passivation and metal overlay contact. Ideally suited for low voltage,
high frequency rectification,or as free wheeling and polarity protection
diodes,in surface mount applications where compact size and weight
are critical to the system.
